For the first time, the Muhlenberg College tracking poll shows a tie between Sen. Arlen Specter and Rep. Joe Sestak in the race for the Democratic nomination. Now, we all know the cautions on evaluating a tracking poll -- snapshot in time, significant margin of error, all that -- but, whoever prevails on May 18, this will be remembered as a significant psychologial moment in the campaign. The incumbent had a huge lead for most of this campaign. The race has closed only in the last week. And most of the interviews for the latest assessment of the Democratic voters' inclinations were conducted before most viewers had a chance to see the new Sestak ad portraying the incumbent as a calculating ally of the Bush administration. The next few days will show whether that's going to move the numbers still further. It's way too early to call this election, but it's safe to say that Chris Borick will be getting a few calls today.
Oh, and in the governor's race, Dan Onorato remains well ahead of everyone but undecided.
